Hubei Sui Resettlement Company, a developer with poor water seepage on the outer wall of Lishui New Town in Hong 'an, wants to delay the five-year warranty period. What should I do?

1. According to Article 7 of the Measures for Quality Warranty of Building Engineering, under normal use, the anti-leakage warranty period for roofing waterproof works, toilets, rooms and external walls with waterproof requirements is 5 years; 2. The commercial house you bought has been leaking continuously for less than five years, which shows that there are quality problems in the roofing waterproof project. According to the law, the minimum warranty period of roof waterproofing project is five years, and the developer must undertake the due repair obligation and be responsible for the losses caused by the owner. 3. Problem handling procedure: (1) The owner should negotiate with the developer and ask the developer to entrust a professional leak-proof company to handle the problem on the grounds that the developer's professional technical level is insufficient to solve the water leakage problem; (2) If the developer refuses to cooperate, complain to the Quality Supervision and Testing Center of the Construction Bureau; (3) If the mediation by the competent department fails, the developer can be sued to completely solve the problem and compensate for the losses. In addition, I want to remind you that when you live in the house for more than 5 years, the roof of the house will leak again. According to the national regulations, "the top floor of a residential building belongs to the public part of the building and should be maintained by the owner", so you should apply for using public maintenance funds for maintenance without your personal contribution.
